Male. — Head seen in front about one and one-quarter times 
as wide as high; frons at its narrowest about twice as wide as 
the eye, measured along inner orbits about as long as its greatest 
width at vertex, the sides converging strongly from vertex to 
fronto-clypeus in upper half and more gradually in lower half; 
inner orbits (parafrontalia) very broad, at their widest more 
than half the width of mediovertex (frontalia), divided into a 
narrow, smooth and bare juxta-ocular zone and a much wider 
alutacous inner zone bearing many soft, yellowish, reclining 
setae in several irregular rows; one stiff, long black bristle at 
inner margin of parafrontalia near upper third and a few sim- 
ilar black bristles (one very long) near fronto-clypeus; one very 
long and thick, black vertical bristle; postvertex (vertical tri- 
angle) very short and wide, semi-elliptical with drawn-out sides, 
the anterior margin even, without median depression or pit, the 
occipital margin nearly straight; apex of fronto-clypeus with 
a narrow, deep median notch, the antero-lateral angles mod- 
erately produced. Palpi very short, thick, about as long as 
fronto-clypeus (measured from ptilinal suture to apical notch), 
covered with many long, black and yellowish setae. Dorsal 
appendage of second antennal segment short, with obtuse apex, 
bearing apically many long, stiff, black bristles, mostly curved 
downward. Thorax: anterior margin broadly concave; pro- 
notum exposed from above as a membranous sclerite, the hind 
margin of which overlaps the anterior margin of mesonotum; 
humeral callosities short, broadly rounded off at apex; median 
notal and transverse mesonotal sutures deep and nearly com- 
plete. Scutellum transversely rectangular (somewhat as in 
Pseudolynchia ) , slightly over three times as wide as its greatest 
length, the anterior (mesonotal) margin nearly straight, the 
hind margin slightly convex medially, somewhat angular at the 
sides, without median groove or depression. Thorax (including 
scutellum) covered uniformly with numerous, short, soft, ap- 
pressed, yellowish hairs, directed backward and each arising 
from a small papula; the hairs are stiffer and black on the 
humeral callosities and notopleura; in addition there are long,
